Specification of Letters Patent.

7 Application filed. August 27, 1914. Serial No. 858,921.

To all whom it may concern:

Be it known that 1, WILLIAM F. Bossnn'r, a citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Apparatus for Opcrating SwitchPoints; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in adjustable connections for switch points and the object in view is to produce a simple and efiicient apparatus of this nature so constructed that the points of a switch may be operated through the medium of suitable switch throwing apparatus, means being provided to allow for the creeping of the rail incident to variations in temperature.

The invention consists more specifically in the provision of adjustable connections for switch points of means whereby snow, ice, cinders or other foreign matter may be effectually prevented from interfering with the adjustment of the parts which are connected to the switch throwing points.

The invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanymg drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which:

Figure 1 isa cross sectional view through the apparatus, parts being shown in elevation. Fig. 2 is a central longitudinal sectional view through the casing in which the adjustable switch operating rods pass. Fig. 3 is a detail view in elevation showing flanged caps forming a part of the invention. Fig. 4 is a cross sectional view centrally through the cap shown in Fig. 3. Fig. 5 is a detail view of a double washer, forming a part of my invention. Fig. 6 is a central cross sectional view through the member shown in Fig. 5. Fig. 7 is a central longitudinal sectional view through the easing showing a slight modification of the apparatus. Fig. 8 is a still different modified form of a detail of the invention. Fig. 9 is a modified form of cap used in connection with the form shown in Fig. 7. Fig. 10 is a sectional view centrally through the cap shown in Fig. 9. Fig. 11 is an elevation of the form of cap shown in Fig. 8, and Fig. 12 is a sectional view centrally through the modified form of cap shown in Fig. 11.

Reference now being had to the details of the drawings by numeral, 1 designates a casting having a flanged portion 2, apertured for the reception of bolts 3, forming means whereby the switch point throwing bar 4 may be securely held to said casting.

A casing, designated by numeral 5, is hollow and provided with a central contracted portion and each end of the casing is flaring as at 6 forming cup-shaped chambers, the inner surfaces of which are con- 4 caved as at 7 and form abutment surfaces. A rod 8, circumferentially threaded, passes through said casing and to this any suitable switch throwing apparatus, not shown, is adapted to be attached, whereby a longitudinal movement may be imparted in one direction or the other to said rod. Cylindrical nuts 9 and 12 are mounted upon said rod and have their inner ends conveXed, adapted to conform to and bear against the concaved surfaces 7 in the chambered end of the casing, and the circumferences of the outer ends of said nuts 9 are squared as at 10, affording means to be gripped by a wrench or other tool to turn the same upon the rod for adjustment.

11, 11 designate jam nuts mounted upon the rod and bearing against the outer ends of the nuts 9 and 12 to hold the same from loosening.

Caps, designated by numeral 15, have each an annular shoulder 16 formed therein and each cap has a laterally extending curved flange 16, in which are formed slits 16, shown clearly in Figs. 3 and 4: of the drawings, and which are provided to form a series of resilient fingers which may conveniently spring over a beading 6 formed about each end of the casing and serve as means for securely holding the caps in place. Said caps are provided with central openings 17 of larger diameter than the diameter of the nuts 9 and 12 and are adapted to receive the short cylindrical portions 18 of the washers 18. The marginal edge of each cylindrical portion 18 has a series of fingers 20 upon one edge thereof which. are bent to engage said shoulders 16? of the caps, as shown in Fig. 2 of the drawings, thus forming a secure means for holding the washers in place. The diameters of the cylindrical parts of the washers are adapted to fit closely about the circumferences of the nuts 9 and'12.

In Fig. 7 of the drawings, I have shown 6* has an annular shoulder formed in: the

inner surface thereof'for thereception of a washer 23. and against which washer the cap 23 bears, thus closing the opening. intermediate the nut 21 and the inner surface of the chambered portion of the casing. In the'form shown in Fig. 7, the jam nut 22 is mounted upon the rod and bears against and is adapted to hold the nut 21 in an adjusted position.

Referring to Fig. 8 of the drawings, I have shown a still different modified form of'cap, designatedby numeral 26, which has an inwardly extending flange 2'6 which telescopes within the casing and is held in place by means of rivets 28, whilethe outer portion of the cap is bent to form a flange 27 receiving a washer 29, the opening in which fits about the circumference of the nutQl, and 22 designates a am nut mountedupon the rod and engaging'the rod 21.

By the provision of the switch point adj usting mechanism described, it' will" be'not'ed that a lost'motion means is provided whereby creeping of the rails'i'ncident to variatIOIIS'lH temperature 1s provlded for, and,

through the medium ofthe caps and washers, snow, ice, cinders and foreign matter may be effectually prevented from lodging inside the casing and thereby avoiding any 7 interference with the adjustment. of th parts. I v
